Abstract:: Copper sulfides (CuxS) are compound semiconductor materials that exhibit considerable variations of optical and electrical properties. Copper sulfide thin films can be used in many applications, such as solar control coatings, solar cells, photothermal conversion of solar energy, electroconductive coatings, and microwave shielding coatings. In this paper, chemical bath deposition...

Abstract:: A novel method of copper indium diselenide nanoparticle (CuInSe₂ NP) synthesis using a two-step, continuous flow, solar microreactor is reported here. This method allows for exceedingly fast heating and short reaction times using only radiative heat transfer from simulated, concentrated solar radiation. Chalcopyrite and sphalerite CuInSe₂ phases have both been...

Abstract:: A novel table-top, microreactor-assisted nanomaterial deposition (MAND™) process, which combines the merits of microreaction technology with solution-phase nanomaterial synthesis and film deposition, was used to grow a nanostructured ZnO anti-reflective coating on a textured silicon substrate from aqueous solution. The subwavelength, anti-reflective nanostructures mimicked the structure and performance of the...

Abstract:: The role of gold nanoparticles supported on ZnO in photocatalytic activity for dye degradation was investigated. To do this, gold nanoparticles supported on ZnO (Au-ZnO) were prepared using a simple co-precipitation method. The prepared nanocatalyst was characterized by high resolution transmission electron microscopy, X-ray diffraction, temperature programmed reduction, X-ray photoelectron...

Abstract:: The reaction conditions for the synthesis of Cu-BTC (BTC = benzene-1,3,5-tricarboxylic acid) were elucidated using a continuous-flow microreactor-assisted solvothermal system to achieve crystal size and phase control. A high-rate synthesis of Cu-BTC metal-organic frameworks with BET surface area of more than 1600 m²/g (Langmuir surface area of more than 2000...

Abstract:: Converting CO2 to valuable materials is attractive.Herein, we report using simple metallothermic reactions to reduce atmospheric CO2 to dense nanoporous graphene. By using a Zn/Mg mixture as a reductant, the resulted nanoporous graphene exhibits highly desirable properties: high specific surface area of 1900 m2/g, a great conductivity of 1050 S/m...
